I ran the chicken through the food processor and then mixed in the sage and some salt. For the pork, I ran about 2/3 of it through the food processor, coarsely chopped the rest, and mixed in the parsley and some salt.

The onions and mushrooms were also chopped up in the food processor and then cooked in some olive oil until "dry". I add a splash of sherry and cooked them some more then seasoned with salt and pepper.

Assembly:

First the ham:

As you can see, it just covers the bottom of the pan. The rest of the pan is lined with the Swiss chard (which had been lightly steamed to soften it and then refreshed in ice water):

The chicken mixture went in first and then I added the green garlic, kind of pushing it into the meat a wee bit:

The mushroom mixture was spread on top of that and then the pork mixture was added:

And here it is, ready to go in its water bath:

It went into a bain marie for 1.5 hours then came out and sat under a foil-wrapped brick until it was cool (about 3 hours). Then it was wrapped tightly and put in the fridge.

I didn't get around to eating it for two days but finally had it for lunch today:
